preheat oven to 400. line baking sheets with parchment. sift together flour, cream of tartar, baking soda, and salt. in the bowl of an electric mixer fitted with the paddle attachment, combine butter and 1 1/2 cups of sugar. beat on medium speed until light and fluffy, about 2 minutes. scrape down the sides of the bowl. add eggs, and beat to combine. add dry ingredients and beat to combine. chill the dough for at least an hour before scooping it.

once the dough has chilled, in a small bowl, combine remaining 1/4 cup sugar and the cinnamon. scoop into tablespoon sized balls and roll in cinnamon sugar. place about 2 inches apart on baking sheets. bake until they are set in the center and begin to crack, about 10 minutes.
